Description

Die Erfindung betrifft eine Luftklappe für Heizungs- und Belüftungsanlagen von Fahrzeugen, insbesondere von Kraftfahr­ zeugen, die mittels eines von einem Sollwert-Potentiometer steuerbaren Elektromotors verstellt wird und ein Geberelement zur Rückmeldung der Klappenstellung aufweist.The invention relates to an air damper for heating and Ventilation systems for vehicles, especially motor vehicles testify by means of a setpoint potentiometer controllable electric motor is adjusted and a transmitter element to report the damper position.

Bei einer bekannten Luftklappe (Zeitschrift "Krafthand", Heft 2, 26. Januar 1980, Seite 4) ist einer elektromotorischen Klappen­ verstelleinheit ein Potentiometer zugeordnet. Dieser Aus­ führung haftet der Nachteil an, daß durch häufige Luftklappen­ bewegungen am Schleifer und an der Widerstandsbahn des Potentio­ meters Verschleißerscheinungen auftreten, die zu Störungen der elektromotorisch betätigten Luftklappe führen können.In a known air damper (magazine "Krafthand", issue 2, January 26, 1980, page 4) is an electromotive flap adjustment unit assigned a potentiometer. This out leadership has the disadvantage that frequent air flaps movements on the grinder and the resistance path of the potentio Signs of wear occur that lead to malfunctions of the can lead electrically operated air flap.

Aufgabe der Erfindung ist es daher, an der Luftklappe solche Vorkehrungen zu treffen, daß auch nach vielzähligen Bewegungen und längerer Betriebszeit keine verschleißbedingten Ausfälle auftreten.The object of the invention is therefore such on the air flap Take precautions that even after numerous movements and longer operating times no wear-related failures occur.

Erfindungsgemäß wird diese Aufgabe durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Weitere, die Erfindung aus­ gestaltende Merkmale sind in den Unteransprüchen enthalten.According to the invention, this object is achieved by the characterizing Features of claim 1 solved. Further, the invention design features are contained in the subclaims.

Die mit der Erfindung hauptsächlich erzielten Vorteile sind darin zu sehen, daß durch das kontaktlos arbeitende Steuer­ element Verschleißerscheinungen am elektrisch/elektronischen System vermieden werden. Der Hall-Geber ist hierzu gut geeignet, da er sich durch Einfachheit und gute Funktion auszeichnet. The main advantages achieved with the invention are to see that through the contactless tax Element signs of wear on the electrical / electronic System can be avoided. The Hall encoder is good for this suitable because it is characterized by simplicity and good function distinguished.  

Durch die Vereinigung des Hall-Gebers des Motors und des Zahnrades zu einer Baueinheit kann diese rationell gefertigt und einfach montiert werden.By combining the Hall sensor of the motor and the Gear to a unit can be rationally manufactured and easy to assemble.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt, das im folgenden beschrieben wird. Es zeigtIn the drawing is an embodiment of the invention shown, which is described below. It shows

Fig. 1 einen Querschnitt durch einen Luftkanal einer Heizungs- und Belüftungsanlage mit der erfindungs­ gemäßen Luftklappe, Fig. 1 shows a cross section through an air duct of a heating and ventilation system with the fiction, modern air flap,

Fig. 2 ein schematisches Schaltbild. Fig. 2 is a schematic circuit diagram.

Eine Heizungs- und Belüftungsanlage 1 umfaßt einen Luftkanal 2 mit einer schwenkbaren Klappe 3. Die Klappe 3 besitzt eine Schwenkachse 4, die bei 5 und 6 am Luftkanal 2 gelagert ist.A heating and ventilation system 1 comprises an air duct 2 with a pivotable flap 3 . The flap 3 has a pivot axis 4 which is mounted at 5 and 6 on the air duct 2 .

Die Schwenkachse 4 ist über eine Nut- und Zapfenverbindung 7 (Steckverbindung) an ein Verbindungsglied 8 angeschlossen, das ein Zahnrad 9 trägt. Das Zahnrad 9 arbeitet mit einer Antriebs­ schnecke 10 zusammen, die mit einem Elektromotor 11 in Wirk­ verbindung steht.The pivot axis 4 is connected via a tongue and groove connection 7 (plug connection) to a connecting member 8 which carries a gear 9 . The gear 9 works with a drive worm 10 , which is in operative connection with an electric motor 11 .

Das Verbindungsglied 8, das Zahnrad 9 und der Elektromotor 11 sind in einem Gehäuse 12 zu einer Baueinheit zusammengefaßt. Das Gehäuse 12 hält bei 13 einen Hall-Geber 14, der mit einem am Zahnrad 9 angebrachten Metallblättchen 15 zusammenwirkt.The connecting member 8 , the gear 9 and the electric motor 11 are combined in a housing 12 to form a structural unit. The housing 12 holds at 13 a Hall sensor 14 which cooperates with a metal plate 15 attached to the gear 9 .

Das Gehäuse 12 ist über geeignete Verbindungsmittel 16, 17 mit dem Luftkanal 2 verbunden.The housing 12 is connected to the air duct 2 via suitable connecting means 16, 17 .

Gemäß Fig. 2 ist der Elektromotor 11 einerseits mit dem Aus­ gang 18 eines Differenzverstärkers 19 und andererseits über den Hall-Geber 14 mit einer ersten Eingangsklemme 20 des Differenzverstärkers verbunden. Eine zweite Eingangsklemme 21 des Differenzverstärkers 19 steht mit einem Sollwert- Potentiometer 22 in Verbindung. Referring to FIG. 2, the electric motor 11 is the one hand, with the off gear 18 of a differential amplifier 19 and the other, on the Hall generator 14 having a first input terminal 20 of the differential amplifier. A second input terminal 21 of the differential amplifier 19 is connected to a setpoint potentiometer 22 .

Wird das Sollwert-Potentiometer 22 manuell oder automatisch verstellt (Warm- oder Kaltluft bzw. Luftmenge), tritt am Ausgang 18 des Differenzverstärkers 19 ein positives oder negatives Signal auf, wodurch sich der Elektromotor 11 dreht und die Luftklappe 3 verstellt. Der Elektromotor 11 steht dann wieder still, wenn das Ausgangssignal am Hall-Geber 14 dem vorgegebenen Sollwert entspricht.If the setpoint potentiometer 22 is adjusted manually or automatically (warm or cold air or air volume), a positive or negative signal occurs at the output 18 of the differential amplifier 19, as a result of which the electric motor 11 rotates and the air flap 3 is adjusted. The electric motor 11 is then at a standstill again when the output signal at the Hall sensor 14 corresponds to the predetermined target value.
